BehaviorThis is a large, brightly coloured Dragonfly. The males are often seen patrolling by a ponds edge or river, where they fight away intruders, crashing into rival males and spiralling through the air. The females are quite inconspicuous when they lay their eggs, but they sometimes give away their spot by clattering up from the reeds. If you look carefully you can sometimes find them ovipositing into some moss, reeds or rotten wood. The males are sometimes very curious and come flying up to you, allowing a close view.
ReproductionThe eggs are laid by jabbing the abdomen into rotting vegetation or wood. The eggs hatch in the spring, after being laid in the previous summer or autumn. The larvae live on small tadpoles and invertebrates. They emerge after 2–3 years.
